Kinetic Energy
NO
Only if car A runs out of gas first.
No, when two cars collide while approaching each other at 60 mph, the impact would be equivalent to one car hitting a solid steel wall at 60mph.Newtons third law states that for every action there is an equal and opposite reaction. When a car is traveling at 60 mph and hits a solid steel wall, the wall applies a force equal to 60 mph back toward the car. This is the same as if a car that is traveling at 60 mph hits another car traveling at 60 mph. In both scenarios, the car is traveling at 60 mph and at the point of collision a force equal to 60 mph is imparted on the car.
Kinetic energy is given by 1/2 M x V2, that is one half mass x velocity squared
Main type is kinetic energy.It may contain sound energy

The kinetic energy of a 22500 lb truck traveling 55 mph is 1/2mv2 is 3084.808kJ.

60/15 = 4The KE of an object is proportional to the square of its speed.Multiplying the speed by 4 increases the KE by (4)2 = 16 .
Only if car A runs out of gas first.
We know that the time traveled is 5 hours, since a car going 10 mph faster travels an extra 50 miles over the same amount of time.Dividing 300 miles by 5 hours, we get 60 mph. Since the car is traveling 10 mph, the car is traveling 70 mph.
A car going 55 mph is traveling at about 80.667 feet per second.
